I took Henri Gomez's request and tried to download the binary mod_jk
from the site he mentioned. I got the same undefined symbol. As I am
using Redhat 7.1 for my Apache server, I decided to take another
person's advice and built mod_jk from source following the JK
documentation.
I still get the 400 error thrown into the mod_jk logs. There is no log
on the Tomcat's side.
Here is the error from the mod_jk log on the Apache side:
